Re: Which scope?
I have both. Leupold 4.5-14X Vari-X III on my .338 and I have a Burris Signature 4-16X on my .30-06. The Burris has better resolution than the Leupold Vari-X III and for Bear I would go with the Burris 3-12 Black Diamond. I don't think you will be disappointed. It is top quality glass, better than Leupold, better than Nikon.
Although the Leupold Premier might be better, but who can afford one?
